I link it to a push button so that upon clicking the button, the value will be displayed. No results was shown in the compilation box. The Yes/No buttons on each line are grouped.
I did the same for lineedit and the values can be printed. Any idea on how to solve this?

Yes, so, the push button emits a clicked signal, you did connect it to a slot to print the text? What does your debugger do? Does it reach the pushbutton clicked slot? In your output pane you could see if the connection had errors and the signal/slot is not setup properly.
And when you click the puchbutton what should happen then? Display the text where?

Not sure why this is not working but we have a rule to name GUI controls that you need to refer to in the code, thus radioButton_22 is not acceptable and should be something like radioButton_Interconnect_Yes and the other radioButton_Interconnect_No. Then at least from the code you can see if you refer to the correct radio button without having to go to the designer and find 22...

So my assumption is that you are actually referring to the correct radio buttons. Then I have no idea why it is not working, it is supposed to.
